Mosquitos tend to be more prevalent at dawn and dusk. To prevent mosquito bites, wear light coloured long pants and long sleeved clothes and use your mosquito repellent of choice. Although cases are less common now and the illnesses are not life threatening, the Zika, Dengue and Chik-V viruses are carried by mosquitos native to the region. Symptoms include headache, fever, rash and joint pain. Pregnant women and people with compromised immune systems should take extra precaution to avoid being bitten as the symptoms can become more complicated.
